FURNACE-FUEL-FEEDING APPARATUS.

Application filed January 10. 1323'. Serial No. 611,713.

In feeding fuel to furnaces particularly pulverized fuel it is desirableto have the apparatus so ftfl'll'lttl that the direction of dischargemay be varied. The present invention accomplishes this and in the preferred form it accomplished by telescoping arcuate tube By sliding thesetubes the direction of the end or inner tube is changed. It is alsodesirable to have a plurality of delivering conduits preferably givingconverging jets and to have the direction of discharge at both jetsvaried. It is also desir able to have a plurality of jets extendinghorizontally. The pres nt invention provides such a. structure. Furtherit is desirable to have the feed through the different jets varied andthis is accomplislwl in the present invention. Other details will appearfrom the specification and claims.

The invention is illustrated in the accompanying drawings as followsFig. 1 shows a plan view of the device partly broken away.

Fig. 2 a side elevation.

Fig. 3 a section of a furnace opening with a pair of the dischargeconduits in elevation partly in section.

Fig. 4 a section on the line AA in Fig. 3.

1 marks the furnace entrance which may be of any desired form, usuallyan opening corresponding to a door opening, and 2 a pulverizer having afan discharge 3 delivering to a conduit 4. The conduit is separated intotwo passages by a plate 5. see dotted lines. Fig. 1, and the air flowthrough each side of the conduit is controlled by a valve 6 mounted on ashaft and actuated by a lever 7 The conduit terminates in a flange 8 onwhich flange a discharge device is secured. This di charge device has aflange 9 which is secured to the flange 8 for connecting the same to theconduit. It is provided with branches 10 and 11 in the form of a Y, oneinclined upwardly and the other downwardly and the relative flow tothese pipes 10 and 11 is controlled by a valve 12. this valve beingmounted on a shaft 13 and actuated by a lever 14. By throwing this valvethe relative quantity going to the pipes 10 and 11 may be varied makingthe flow to the pipe 10 greater or less or the pipe 11 greater or lessas desired. The lever op crates over a slotted plate 20 through which alocking screw 19 extends. The lever may be locked in any adjustedposition by tight citing the screw. Thus the flow of fuel and airthrough the discharge tubes 10 and 11 may be varied relatively to eachother.

The tube 10 and 11 are of arcuate shape A tube 21 also of arcuate formis telescopically mounted on the tube 10. It is supported by guiderollers 24-. in the opening 1. It will readily be Seen that by slidingthe tube 21 on the tube 10 the direction of the discharge is varied aswell as the point of discharge. A tube 23 of arcuate shape is mounted onthe tube 11 and this is supported within the opening on. rollers 24. RVsliding the tube 23 along the tube 11 the dirlction of discharge of thistube may be varied as well as the point of discharge. The tubes 21 andare provided with handles 25 to add to the convenience of adjusting themand the e handles are secured to plates 26 arranged on the tube. A screw27 extends through the plate 26 against the inner tube thus locking thetelescoping tubes in any adjustment that may be desired. It will benoted that there are two pairs of these discharge tubes. one

connected with each passage in the conduit 4 and it will be noted thatthe discharge conduits of each pair converge so that not only can eachdischarge be adjusted as to direction but they may be adjustedrelatively to each other and the volume of air through each dischargemay be varied relatively to the other discharge openings.

What I claim as new is 1. In a furnace fuel feeding apparatus.

the combination with a furnace: of a fuel and air conduit leading to thefurnace including means comprising arcuate telescoping tubes for varyingthrough the sliding adjustment of one tube upon the other the 5direction of discharge of the conduit into the furnace.

2. In furnace fuel feeding apparatus. the combination with a. furnace:of a fuel and air conduit leading to the furnace including meanscomprising arcuate telescoping tubes for varying through the slidingadjustment of one tube upon the other the direction of discharge of theconduit into the furnace: and means for locking the tubes in admeanscomprising arcuate telescoping tubes for varying through the slidingadjustment of one tube upon the other the direction of discharge of theconduit into the furnace; and supports within the furnace for thesliding telescoping tube.

'1'. In a furnace fuel feeding apparatus the combination with a furnace;ot a pair of not and air conduits. each of the tuet and air ronduitscomprising arcuatc telescoping tubes for 'anving through the slidingadjustment of one tube upon the other the (11- reetion of discharge ofsaid conduits.

5. In a furna tuei feeding apparatus, the combination with a furnace; ofa pair of fuel and air conduits comprising arcuate telescoping tubeshaving converging discharge openings. the direction of discharge beingvariable through the sliding adjustment of the telescoping: tubes oneupon the other.

In testimony whereof I have hereunto set in hand.

THEODORE JOHNSON.
